Hashing passwords

Sooner or later, most websites have to implement a login system of some kind. At this moment
at latest, it is inevitable to think about how the passwords can be stored safely. Even big and
well-known internet portals stumble over this challenge again and again, and the internet provides
a lot of bad or outdated examples (this article was last updated in 2016).

I reworked a presentation of this topic to a tutorial. It is an attempt to present the
necessary steps, so that all should understand them, security comes from
understanding after all. The tutorial allows a bit to play with SQL-injection, and then describes
the usage of salt and pepper for hashing.
